Expandable speaker assemblies for portable media devices

Expandable speaker assemblies for portable media devices description/claims

The embodiments herein relate to speaker accessories compatible for use with portable media players (PMPs) non-exclusively including smart phones, handheld game consoles, and digital audio and video players capable of storing and playing files in one or more media formats. More specific embodiments relate to speaker assemblies designed for use with portable media players that are configured to be used in multiple orientations.

Portable media players (PMPs) are handheld electronic devices that are capable of storing and playing files in one or more media formats. In general PMPs are configured to play audio and/or video files. Additionally, PMPs can also display image files, including pictures, spreadsheets, word processing documents, drawings, graphs, web pages, and the like. Data files are typically stored on a hard drive, microdrive, or flash memory within the PMP. Various portable media players include the ability to record video and audio, and some have built-in card readers like SD or MMC, which makes it convenient to upload media directly to the player, or the memory is used as extra capacity.

Typical video formats PMPs can be configured to play non-exclusively include MPEG, DivX, Xvid, AMV and SigmaTel Motion Video (SMV) files. Typical audio file formats PMPs can be configured to play, non-exclusively include MP3, WAV, Advanced Audio Coding (ACC) and Ogg Vorbis. Typical digital image formats PMPs can be configured to display non-exclusively include BMP, JPEG, PDF, and GIF, for example.

While most PMPs are capable of playing audio, because of their relatively small size and power needs, often times the speakers that are built into the PMP are inadequate, if they exist at all. Minimally powered, or small built-in speakers on a PMP make it difficult for multiple listeners to simultaneously enjoy an audio file. To address this issue, removable speaker assemblies for PMPs have been designed to allow multiple listeners to simultaneously hear an audio file.

One example of an existing speaker assembly configured for a PMP is provided in U.S. Pat. No. 7,230,822, to Langberg, et al, which is hereby incorporated by reference in its entirety. Unfortunately, the speaker assembly disclosed in Langber, et al., and other existing speaker assemblies, are configured for PMPs that display images and videos files in a single orientation. Recent technological developments in PMPs however, now allow for the screen to display images and video files in multiple orientations. Examples of PMPs that currently display images and video files in multiple orientations (e.g., vertical and horizontal or portrait and landscape) non-exclusively include Apple iPhone and Apple iPod Touch, for example.

Thus, there is a need in the art for releasably attached speaker assemblies configured to work with PMPs that display images and/or video in multiple orientations. Accordingly, one object of the teachings herein is to provide a releasably attachable speaker assembly operably coupled to a PMP that can operate while the PMP is positioned in a plurality of orientations. More specifically, in advantageous embodiments, the teachings herein are directed to speaker assemblies that can expand past the coupled PMP in its widest orientation such that the body of the PMP does not significantly block, or overlap the speakers. Further objects of the invention, allow for a compact speaker assembly that is collapsible and expandable, to make it easier for the user to handle and transport. More specifically, in preferred embodiments the speaker assemblies provided herein can be configured to have the same, or substantially the same, height and width as the attached PMP, or even smaller.

Embodiments herein are directed to speaker assemblies having a housing configured to utilize a power source and being operably connected to 1 or more speakers having means for expanding and contracting, and further including means for releasably attaching and operably coupling to a portable media player (PMP), such that audio can be transmitted from the PMP through the 1 or more speakers. More specifically, speaker assemblies herein can include means for releasably attaching to said PMP that are configured to rotate, such that a user can view the PMP in multiple orientations

In further embodiments, the means for expanding and contracting are operably coupled to said means for releasably attaching to said PMP, such that the speakers are configured to expand and contract based on the rotation of the PMP. In further embodiments, the means for releasably attaching to said PMP are operably coupled to a rotating central gear within the housing that is configured to expand and contract the speakers based upon clockwise or counter-clockwise rotational direction. Additionally, the gear can include two toothed quadrants positioned on opposite sides from each other and are complementary to toothed sections on extension arms coupled to 1 or more speakers. Additionally, the means for expanding and contracting can be configured to expand the 1 or more speakers to a position beyond the body of the PMP and contract the 1 or more speakers to a position behind the body of the PMP.

Additional embodiments relate to speaker assembly having a housing configured to utilize a power source and being operably connected to 1 or more speakers having means for expanding and contracting, and further including means for releasably attaching and operably coupling to a portable media player (PMP) having a substantially rectangular screen that can display video or images in both a vertical and horizontal orientation, such that data can be transmitted from the PMP through the 1 or more speakers. In other embodiments, the means for releasably attaching to said PMP can be configured to rotate, such that a user can view the PMP in both said vertical and horizontal orientation. Further means for expanding and contracting are operably coupled to the means for releasably attaching to said PMP, such that the speakers are configured to expand and contract based on the rotation of the PMP.
